Ultraviolet B (UV-B) light is a potential stress factor in plants, but how plants coordinate growth and UV-B stress responses is not well understood. Here we report that brassinosteroid (BR) signaling...
2023年7月28日,The Plant Journal在线发表了南京农业大学作物遗传与种质创新利用全国重点实验室油菜遗传育种团队的最新研究成果“Mutation to a cytochrome P450-like gene alters the leaf color by affecting the heme and chlorophyll biosynthesis pathways in Br...
Caffeine is a characteristic bioactive compound in tea and coffee plants, which is synthesized and accumulated extensively in leaves and seeds. However, little is known about the regulatory mechanism ...
Theanine is a unique major amino acid in tea plants responsible for umami taste and mental health benefits of tea. However, theanine biosynthesis and physiological role in tea plants are not fully und...
Theanine, one of the most important components of teas, confers the umami taste and relaxation effect of tea infusion. As a non-proteinogenic amino acid, theanine solely accumulates to high levels in ...
Theanine and flavonoids (especially proanthocyanidins) are the most important and abundant secondary metabolites synthesized in the roots of tea plants. Nitrogen promotes theanine and represses flavon...
缩节胺(MC)作为一种赤霉素生物合成抑制剂,可以增加棉花对钾离子的吸收,从而对棉花生长产生积极调节作用,但是潜在生理机制尚不清楚。本研究利用非损伤微测技术测定表明,除了增加根生物量之外,MC浸种还可以通过增加钾离子流入和/或减少幼苗根尖的钾离子外排来增加钾离子吸收。此外,该研究发现,MC处理可以引起质膜超极化,可以通过增强H +-ATPase的基因表达(HA2/5/11)、蛋白积累(GhAHAs总...
Shading was thought as an effective approach to increase theanine in harvested tea shoots. Previous studies offered conflicting findings, perhaps since the integration of theanine metabolism and trans...
The growth of leaves and biosynthesis of characteristic secondary metabolites are critically important for tea production and quality control. However, little is known about the coordinated regulation...
Auxin is a phytohormone essential for plant development. However, our understanding of auxin-regulated endosperm development remains limited. Here, we described rice YUCCA (YUC) flavin-containing mono...
Salicylic acid (SA) has long been known to be essential for basal defense and systemic acquired resistance (SAR). N-hydroxypipecolic acid (NHP), a recently discovered plant metabolite, also plays a ke...
Two signal molecules, salicylic acid (SA) and N-hydroxypipecolic acid (NHP), play critical roles in plant immunity. The biosynthetic genes of both compounds are positively regulated by master immune-r...
Tocopherols are lipid-soluble antioxidants synthesized in plastids of higher plants and other photosynthetic organisms. The four known tocopherols alpha-, beta-, gamma- and delta-tocopherol differ in ...
Leaf angle is a key parameter that determines plant architecture and crop yield. Hormonal crosstalk involving brassinosteroid (BR) plays an essential role in leaf angle regulation in cereals. In this ...
Cuticular waxes that cover the above-ground parts of land plants are essential for their survival in terrestrial environment. However, little is known about the regulatory mechanisms underlying cuticu...
